(BQ) In this research work two different materials have been used as work pieces. These EN8 and D3 steel materials have been machined in an Electrical discharge machine which has wide application in Industry fields. The important process parameters that have been selected are peak current, pulse on time, die electric pressure and tool diameter. The outputs responses are material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR).

The number of episodes of diabetic ketoacidosis (DKA) is a Parkville, Melbourne, Australia significant outcome measure for diabetes care. We ascertained patterns of admission due to DKA over 15yr to determine whether this indicator of diabetes care had improved in parallel with clinical practices. Between 1 January 1985 and 31 December 1999, 630 admissions were reviewed. We subanalyzed these admissions according to whether the patient was...

Cố định vi khuẩn bằng hydroxide kim loại làm tăng độ nhạy của phương pháp PCR khi phát hiện vi khuẩn trong thực phẩm. Vi khuẩn ở nồng độ thấp không qua nuôi dưỡng có thể phát hiện được bằng phương pháp PCR nhờ cô đặc vi khuẩn từ thực phẩm bằng hydroxide kim loại. Enzyme DNase I được sử dụng để loại bỏ DNA từ vi khuẩn sống, do đó phương...

A back -propagation artificial neural net has been trained to estimate the activity values of a set of 18 N-alkyl-N-acyl- -aminoamide derivatives from the results of molecular mechanics and RHF/PM3/SCF MO semi-empirical calculations. The input descriptors include molecular properties such as the partition coefficient P, 3d structure dependent parameters, charge dependent parameters, and topological descriptors.

A complete and permanent hydrophilic modification of poly (ethyleneterephthalate) (PET) films is achieved by argon-plasma irradiation, subsequently grafting acrylic acid (AA) in vapor phase onto their surface. Both Ar plasma irradiation alone and post grafting AA rendered a complete hydrophilicity to PET surfaces. However, the hydrophilicity of the PET surface, only treated with the Ar plasma, is not permanent. In contrast, PET films,...
